Keith,
Spent long time in DC area and triple digit temps not too often, multi days in high 90's yes! high humidity all summer yes! JMO.. Triple digit temperatures belong in Arizona desert but usually with low humidity a different animal all together. Just putting out my life long experience with Mid-atlantic conditions and fun in transition zone, no more or less.... here in Chicago area we saw dollar spot in the rough, places looking like puffs of white cotton candy, or even a light snowfall sometimes seen back home in DC area. It was crazy rare for sure here in Chicago area. This was a 3 day temperature and humidity event that set records over history of weather in this area. The picture posted said it all! Now passing and smiles on many faces
